重组人卵磷脂胆固醇酰基转移酶(Human LCAT)

LCAT Human
Lecithin-Cholesterol Acyltransferase Human Recombinant
Catalog No. ENZ-380

Synonyms:
Phosphatidylcholine-sterol acyltransferase, Lecithin-cholesterol acyltransferase, Phospholipid-cholesterol acyltransferase, LCAT.

Introduction:
LCAT is an extracellular cholesterol esterifying enzyme, lecithin-cholesterol acyltransferase. The esterification of cholesterol is required for cholesterol transport. LCAT is a essential enzyme in the extracellular metabolism of plasma lipoproteins.

Description:
LCAT Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 426 amino acids (25-440) which includes a 10 amino acid His Tag fused at N-terminus and having a total molecular mass of 48.3 kDa.
LCAT Human Recombinant is purified by proprietary chromatographic techniques.

Source:
Escherichia Coli.

Physical Appearance:
Filtered White lyophilized (freeze-dried) powder.

Formulation:
The LCAT protein was lyophilized from 0.4μm filtered solution at a concentration of 0.5mg/ml containing 0.05M Acetate Buffer pH-4.0.

Solubility:
Add 0.1M Acetate buffer pH4 to prepare a working stock solution of approximately 0.5mg/mL and let the lyophilized pellet dissolve completely. For conversion into higher pH value, we recommend intensive dilution by relevant buffer to a concentration of 10μg/mL. In higher concentrations the solubility of this antigen is limited. Product is not sterile! Please filter the product by an appropriate sterile filter before using it in the cell culture.

Stability:
Lyophilized LCAT although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution LCAT should be stored at 4°C between 2-7 days and for future use below
-18°C.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.

Purity:
Greater than 95.0% as determined by SDS-PAGE.
